[REBOL] Trying to compose a block out of global and local bindings

From: princepawn::lycos::com at: 7-Sep-2000 13:02

The 6th message from Elan in this thread contains a useful explanation for beginners on the danger of re-defining "built-in" Rebol words.


Be careful to read Ladislav's clarifications in messages 7 & 
8 on contexts.



>> letter2: func [b /local name] [foreach n ["sally" "sue"][ name: n print reform reduce 
b] ]

>> form
== ["hi" name "welcome back"]

>> name
== "bob"

>> letter2 form
hi bob welcome back
hi bob welcome back


... the only problem is I was hoping that the loop values in letter2 would take precedence 
over the globally bound value of name and allow me to create a form letter of sorts.

Could anyone help with this please?
